Description
Technical field
This utility model belongs to pipeline tapping technical field, specifically, relates to a kind of Pressurized driller for pipeline drill bit.
Background technology
Pressurized driller for pipeline is a kind of normal work not stopping pipeline under system pressure, carries out perforate and divides to install
The equipment of branch pipe(tube).Drill bit structure in its perforate is relatively big to perforate influential effect, drill bit in use, the cut end of drill bit
Inside and outside wall is big with pipe friction coefficient, and therefore it is impaired relatively conventional and serious, and once cut end is impaired, and impact uses,
The most whole drill bit i.e. can be eliminated, and causes the wasting of resources, improves perforate cost especially.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of Pressurized driller for pipeline drill bit, fall
Low drill bit loss percentage, can reduce perforate cost simultaneously, economize on resources.
This utility model purpose is achieved in that a kind of Pressurized driller for pipeline drill bit, and it it is critical only that: includes cutter
Body, this cutter hub cylindrically, close, and its other end opening, the blind end end face of this cutter hub has centre bore by described cutter hub one end
With a circle fixing hole, described fixing hole is circumferentially distributed around described centre bore, the edge indentation of described cutter hub opening, often
All having on individual sawtooth and inlay mouth, this is inlayed to inlay on mouth and is fixed with blade.
Using said structure, drill bit uses blade mosaic texture, and after breaks down, available acetylene oxyacetylene metal-cutting is got off, then installs solid
Fixed new blade, can reuse after polishing is put the first edge on a knife or a pair of scissors, thus cutter hub can reuse, and has saved cost for user, subtracts
Lack the waste of resource, for user with considerable economic benefit of knowing clearly.
Insert is to described cutter hub lateral offset 1mm, and its adjacent blade then to described cutter hub offset inboard 1mm, depends on
Secondary being alternately distributed forms side set structure.Use above-mentioned side set structure, stop pipe friction cutter during alloy bit cutwork
Intracoelomic cavity and outer wall, alleviate load during tapping machine work, improve work efficiency.
Insert is carbide blade, this blade be welded on described in inlay in mouth.Use said structure, blade exchange
More convenient.
Having at least 3 sled holes on the sidewall of above-mentioned cutter hub, described sled hole centrosymmetry is distributed.Use said structure,
Cut the circular clout block got off on metallic conduit to be taken out of by centre drill, because pipeline outer wall becomes arc-shaped, perforate to complete rear cutout
The circular clout block chipped away will unfold expansion, causes clout block to be stuck in cutter hub inner chamber, can be prized by clout block by sled hole.
Beneficial effect:
This utility model one Pressurized driller for pipeline drill bit, blade exchange is convenient, makes cutter hub to reuse, and saves
Cost, decreases the waste of resource, and side set structure has stopped during alloy bit cutwork pipe friction cutter hub inner chamber and outer
Wall, alleviates load during tapping machine work, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Embodiment:
As illustrated in fig. 1 and 2: a kind of Pressurized driller for pipeline drill bit, being made up of cutter hub 1, this cutter hub 1 is cylindrically, described
Cutter hub 1 one end is closed, its other end opening, and the blind end end face of this cutter hub 1 has centre bore 2 and a circle fixing hole 3, described solid
Determine hole 3 to be circumferentially distributed around described centre bore 2, the edge indentation of described cutter hub 1 opening, each sawtooth all has edge
Embedding mouth, this is inlayed to inlay on mouth and is fixed with blade 4.This blade 4 is inlayed in mouth described in being welded on.Described blade 4 is to described cutter
Body 1 lateral offset 1mm, its adjacent blade 4, then to described cutter hub 1 offset inboard 1mm, is alternately distributed formation side set knot successively
Structure.Having 3 sled holes 5 on the sidewall of described cutter hub 1, described sled hole 5 is centrosymmetric distribution around the central shaft of described cutter hub 1,
Certainly the number in sled hole is alternatively 4,5,6 or 7, as long as ensure that the clout block that can sufficiently prize cutter hub inner chamber.
It is last it should be noted that foregoing description is only preferred embodiment of the present utility model, the common skill of this area
Art personnel, under enlightenment of the present utility model, on the premise of this utility model objective and claim, can make
Represent as multiple types, within such conversion each falls within protection domain of the present utility model.
